Hakata Gion Yamakasa is a prominent festival held annually from July 1 to July 15 at Kushida Shrine in Fukuoka City. With a history spanning over 770 years, it is recognized as a UNESCO Intangible Cultural Heritage. The event originated in 1241 as a religious rite to ward off a plague and has since evolved into a high-energy competition between the traditional districts, or nagare, of Hakata.
The festival features two distinct types of floats. Beginning July 1, several kazari-yamakasa are displayed throughout the city. These are stationary, decorative floats that stand over ten meters tall, intricately adorned with figures from Japanese history and mythology. In contrast, the kaki-yamakasa are smaller, functional floats designed to be carried at high speeds through the city streets by teams of men.
The festival reaches its climax with the Oiyama race, which begins precisely at 4:59 AM on July 15. During this event, seven teams compete to carry their heavy floats along a five-kilometer course in the fastest possible time. As the teams navigate the route, spectators splash water on the runners in a practice known as mizu-iwai, which serves both to cool the participants and provide ritual purification. The event is characterized by the rhythmic “Oisa!” chants and the impressive coordination required to maneuver the massive floats through narrow urban corners, representing a significant display of local community spirit and physical endurance.
